| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current behaviour is to generate the IT instruction only for Thumb-2 code. However, the kernel helpers in entry-armv.S are compiled to ARM in a unified syntax file (if THUMB2_KERNEL). Recent compilers warn about missing IT instruction in unified assembly syntax files.

* | | omap: Disable serial port autoidle by defaultTony Lindgren2010-02-031-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the omap serial clocks are autoidled after 5 seconds. However, this causes lost characters on the serial ports. As this is considered non-standard behaviour for Linux, disable the timeout. Note that this will also cause blocking of any deeper omap sleep states. To enable the autoidling of the serial ports, do something like this for each serial port: # echo 5 > /sys/devices/platform/serial8250.0/sleep_timeout # echo 5 > /sys/devices/platform/serial8250.1/sleep_timeout ...

The additional pins exist in omap36xx_cbp_subset, but are not initialized as the superset is missing these offsets. This causes the following errors during the boot: mux: Unknown entry offset 0x236 mux: Unknown entry offset 0x22e mux: Unknown entry offset 0x1ec mux: Unknown entry offset 0x1ee mux: Unknown entry offset 0x1f4 mux: Unknown entry offset 0x1f6 mux: Unknown entry offset 0x1f8 mux: Unknown entry offset 0x1fa mux: Unknown entry offset 0x1fc mux: Unknown entry offset 0x22a mux: Unknown entry offset 0x226 mux: Unknown entry offset 0x230 mux: Unknown entry offset 0x22c mux: Unknown entry offset 0x228 Fix this by adding the missing offsets to omap3 superset.

Before suspend and upon resume, it uses a weak function read_persistent_clock() to determine the amount of time that elapsed during suspend. This function was not implemented on OMAP, so from the timekeeping subsystem perspective (and thus userspace as well) it appeared that no time elapsed during suspend. This patch uses the 32k sync timer as a the persistent clock. NOTE: This does *NOT* fully handle wrapping of the 32k sync timer, so more than one wrapping of the 32k sync timer during suspend may cause problems. Also note there are not interrupts when the 32k sync timer wraps, so something else has to be done.

Fixed by writing the last register to the save area. Also, optimized the delay loop for the HW save to include an udelay(1), which limits the number of unnecessary HW accesses to SCM register area during the save.
